General description.

Described in general terms, the machine embodying the present invention is one which is particularly suited for use by tellers in savings banks or similar institutions.

In institutions of this type, the principal transactions handled by the tellers consist of entering either withdrawals or deposits, and it is, therefore, the principal function of the present machine to take care of such transactions.

If, for instance, a customer desires to make a deposit, the teller first withdraws the customers account card from his file, and sets up on the keyboard the customers account number, together with the amount of the customers old balance, as shown by the card. The machine is operated, and the old balance is entered upon an adding and subtracting totalizer. It is also printed upon the detail strip, customers account card and his pass book. The amount of the deposit is then set up upon the keyboard, the deposit key assigned to the. particular teller operating the machine at that time, is depre sod and the machine released, whereupon the amount of the deposit is added to the amount of the old balance, which has previously been entered on the adding and subtracting totalizer. The total lever is then moved to the balance position and the machine released, whereupon the total of the old balance and the deposit, which forms the new balance, will be printed upon the detail strip, customers card and pass book, and at the same time, the adding and subtracting totalizer will be returned to zero. The depression of the deposit key controls the selection of a totalizer, which will also receive the amount of the deposit, and another total-- izer is automatically selected which receives the totals of the deposits of all of the tellers.

Practically the same procedure is carried out when the customer desires to make a withdrawal. In this case the old balance is first entered upon the adding and subtracting to talir cr and printed as above described. The amount of the withdrawal then set up on the keyboard and the withdrawal key corresponding to the teller handling the transaction is depressed. Vhen the machine operated, the amount of the withdrawal is subtracted from the amount of the old balance standing on the add ing and subtracting t :al iZer. Then when'the total lever is moved to the balance position, and the machine oper ated, the new balance will be printed, as above described, and the adding and subtracting totalizer returned to Zero. The withdrawal key also controls the totalizer, which accumulates all the Withdrawals of that particular teller and the withdrawal key automatically selects another totalizer in which the total withdrawals handled by all the tellers are accumulated.

Operating mechanism.

The machine is operated by either an electric motor or a crank in the usual manner, and it is thought to be unnecessary, in view of the patents and applications above referred to, to include any description of the operating mechanism in this application. It is thought to be sutiicient to state that the operating n'ieohanism drives a main drive shaft 77, which in turn, operates the mechanism of the machine.

Amount keg s.

Any number of banks of amount keys may be provided in the present machine, depending on the capacity desired. These amount banks are identically the same as the amount banks shown and described in the above patents and applications, and therefore but a brief description thereof will be given herein. The amount banks are all duplicates of each other, and Fig. 1 shows one complete bank. Keys 101 are slidably mounted in key frames 102, supported at their lower ends upon a rod 103, and at their upper ends upon a rod 104. Each of these keys cooperates with a detent bar 105, and a locking plate (not shown), and is held in its normal outer position by means of a spring in the usual manner. Each of these keys has a shoulder, which when the key is depressed, contacts with a corresponding pin on the detent 105, thereby rocking the do tent downwardly until the shoulder on the key has passed the pin on the detent, whereupon the detent will move upward far enough to prevent the key from returning to its normal outer position. The keys are released near the end of the operation of the machine by means of a rod 108, which is carried by a plurality of arms 109, fast on a T818218, shaft 0 1:. The rod 108 cooperates with a tail 111 of the link supporti the upper end of the detent bar 105, and when the shaft 01 is rocked counter-cloclzwise by means to he later described near the end of the operation, the detent bar will be moved downwardly far enough to permit the shoulders of the keys to pass the pins carried by the detent bar, and thereby be restored to their normal positions.

Cooperating with. each bank of amount keys is a zero stop pawl 112, (hi 1) the function of which will be do? 5t ibed later. These )awls are fast on short shai s 713, mounted in the key banks. 'lhcse shafts 113 also carry arms 11%, which in turn support pins 115, cu gaged by hooked links 116, pivoted to the key banks, and also pivotally connected to the lower ends of the detents 105. The zero stop pawl 112 is normally in the position shown in Fig. 1, but when a key 101 is depressed, the lowering of the detent bar 105 rocks the hooked link 116 clockwise, which through pin 115, arm 11 1- and shaft 113, rocks the zero stop pawl 112 counter-clockwise to its inelfec- '1 is 1101;111:11- 05; effective 1 1.1

When this occurs, the latch 1239 will be moved forwardly out of engagement with the shoulder nd the forward end of sa d latch will engage with one of a plurality of notches 12412 in a serrated bar 12-1-3. If no key in the deposit bank or withdrawal bank (not shown) is depressed the zero stop pawls 1112 for these banks will be engaged by the ends of lovers 2T3 slotted to receive pins 272 on the bell crankl vers 12 1-1 (see llig'. 3), and disconnect the latches 1239 for these banks in the zero position, as in the amount banks. If a key in one of these banks has been depressed, the corresponding zero stop pawl for that bank will be rendered inoperative.

Appropriate to each amount differential mechanism is a beam 251, pivoted at one end to the differei'itially movable member 233, and bifurcated at its opposite end to straddle a stud carried by a link 253. The beam 251 is operated by a roller 250, carried by the Y shaped. lever 229. At its lower end, this link is pivoted to an arm 2541, fast to a spiral segn'ient 255, loose on a rod 256 supported by the machine side frames.

The beam 1251 is bifurcated at its opposite end to straddle a stud 1252 on a link 1253 pivoted at its lower end to an arm loosely mounted on the shatt 256. A sp ral segmental gear 1255, also journaled on the shaft 256, is fast to the arm 1254 and meshes with a spiral i 'iiion 1257 fast on the end of a shaft 1258. .L 1e shafteXtends into the printer and, means of mechanism not shown herein, sets up type wheels (also not shown) for 1 'purposes.

The machine to which the present invention adapted to be applied, is provided with an adding and subt 'acting totalizer, such as is shown in Fig. 17 of applicants co-pending application, Serial No. 610,273. This same type of totalizer is also illustrated and described in the patent to Fuller, No. 1,242,170.

11 brief description of this totalizer will now be given.

The adding and subtracting totalizer illustrated in Fig. '7 includes a plur lity of pairs of totalizer wheels 2529 and 830 rot-atably mounted on a tube 331. Two brackets 332 and 3533 support the tube 331 on a shaft 334:, the ends of which shaft traverse guide slots (not shown) in plates attached to the side frames of the machine. A rod 335 connects the brackets and 333, and with the tube W1 i'ms a totaliz ,r frame slidable longio i the shaft 331 for the purpose of 1161' of the nets of totali'lier wheels are t be engaged with the actuator small beveled nu ion 33'? mountei'l on a the tube 331, meshes it led near. 2336 for each pair of totalnc: wheels 3:35) and 330 in such a manner that iei one of the wheels 5322 or 330 rotated 11] one direction, its mate f ied an equal distance in the opposite di- ZJe/Imzcc 50.1170 differential.

The differential mechanism which cooperates with the balance keys is identically the same as the differential mechanism for the deposit and w rhdrawal banks, with one exception which will be hereinafter mentioned.

The differential mechanism for this bank is for positioning the adding and subtracting totalizer that either the adding pinions 330 or the sulfitracting pinions 329 thereof will be "u alinemcnt with the differentially movable racks of the amount differential mechanism. Tier, are no keys for disconnecting the l? ch of the differential mesh: nism appropriate to this bank, as there a e in the other banks of the machine. The latch is disconnected under the control of certain keys in the deposit and withdrawal banks on addi i o suhtracti 1g operations, and under control of the total lever on totalizing operations.

Sim larly. the upwardly extending arm of the angularlever 1273 disconnects the latch 2239 from the driving; segment 2238 in the total or fifth position, on its upward ravel, by striking the pin 276 which is moved nto the path thereof by the spring; when the otal control lever 135 is adjusted from its dding position to any of its several total id sub-total taking positions.

lVhen the bell crank lever 2245 is rocked counter-clockwise, the latch 2289 is disconnected from the segment 2238 and at the same time, the forward end of said latch moves into engagement with a particular notch in a serrated bar de 'iendine upon which of the several means employed to rock the hell crank lever 224.1 to disconnect the latch. The driving segment 2238 then continues its re or excursion and when, on its return movement, the shoulder on the segment arrives opposite the foot of the latcl 2239, a spring (not shown) withdraws the latch fr in the notch 22%2 in the serrated bar 2243 and engages it behind the shoulder on the segment 2298. The segment LL38 continues its return travel to home position, and carries the latch and differentially mova )le arm 1249 therewith. I

Shortly after the commencement of this movement, the upper edge of the beam contacts with the stud 1232, which forms a fulcrum for the beam, whereby continued upward movement; of the diti'erential arm 1249 lowers the link 1253. This movement of the link 2253 rocks the toothed segment 2259, shaft 261 and arm 3&0 (Fig. 3) in a clockwise direction, the aligner being disabled, which movement serves to lower the link 3&1 (F 3 and 7) to rotate the drum cam 34 1-. Due to the angular configuration of the cam groove it will, when moved to a position wherein any one of the three apertures 3 1 8 in the lower part thereof opposite the rod 3&5, slide the adding and subtracting totalizer to the right, as viewed in Fig. 7, to bring the adding wheels 330 into co-operative relation with the actuator racks 23 1-. The holes 348 are tor the purpose of accommodating the end of the rod 345 when the totalizer is moved into engagement with the actuator racks 234: by means not herein disclosed.

The angular portion of the drum cam 34in (Fig. '7) is provided in order to shift the adding and subtracting totalized to ect either the adding wheels or the subtracting wheels for engagement with the totalizer actuators 234. Therefore, only two positions 0]": the cam, and consequently, of: the differentially movable arm 124-9 (Fig.3) are necessary to select the adding wheels and the subtracting wheels. However, the balance bank differential mechanism 3) which positions the drum cam 34 i 7) sets up type wheels (not shown) and selects columns in which the imprint is to be made, by means of the shaft 2258, and since it is desired to print several ditlerentcharacters, and to print in different columns, it is necessary to provide means for disconnecting the lat-ch 2239 of this bank from, its driving segment 2238 in a corresponding number of positions. Only one of these positions, the Zero position, selects the subtracting wheels 329. The upper three positions, that is, the positions corresponding with the positions of the 5, 7 and 9 keys of an amount bank, all select the adding wheels 330 and set the type wheels to print corresponding characters.

The adding and subtracting totalizer is normally so positioned that the subtracting pinions 329 thereof are in position to co operate with the actuators 234:. It can be seen, therefore, that if an operation which involves subtraction is to be performed, such as a withdrawal operation, the totalizer need not be moved, and it is, therefore, necessary to provide means to disconnect the latch 2239 of the balance bank differential, which selects the position for the adding and subtracting totalizer, in the Zero position. T1, however, a transaction involves addition, it is necessary to disable the means for disconnecting the latch of the balance bank differential in its zero position, and to provide means for disconnecting this latch in the positions appropriate to the character of the transaction, which will, in all cases, not involving withdrawals, move the adding and subtracting totalizer to the adding position.

Taking for example, operation which involves the making of a deposit, the operator first depresses the old balance key, which is the uppermost key in the bank shown in Fig. 2. The depression of this key automatically controls mechanism for the purpose of disconnecting the latch 2239 of the balance bank differential in the seventh position. The mechanism for disconnecting the latch in this position consists of a bifurcated arm 266 2 and 5) loose on a shaft 180. The bifurcated end of arm 266 straddles a pin 267, carried by the shank of th old balance key in the deposit bank. The arm 266 is connected with another arm 288 by a yoke 269. It can be seen from Fig. 2 that when the old balance key is depressed, pin 267 will rock the arm 266 counter-clockwise and through the yoke 269, will rock the arm 268 to the same extent, which will position the end 270 of this arm in the path of movement of the lever 241, appropriate to the balance bank. Therefore, when the lever 2 1-1 comes into contact with the end 230 of the arm 268, the latch 2239 will be disconnected from its driving segment 2238. The disconnection of the latch at this point positions the adding elements 330 oi the adding and subtracting totalizer to receive the amount of the customers old l alauce. in this position also, the corresponding type wheel (not shown) is positionedto print a character symbolic ot the transaction just completed.

The amount of the deposit i then set up on the amount keys 101, and a deposit key 119 is (lOPl'GSSCil. Then when the macl'inc is operated, the diil erential mechanism for the balance bank moves to the ninth posi -ion, as the Zero stop pawl 2112 has been. moved to inetiective position by the depression of the deposit key, and there are no other obstructions in its path. 7

Vt hen the latch 2239 reaches the ninth position, it is disconnected from its driving segment 2238 by contact with a fiat stud 271 on what would normally be the key frame. he disconnection of the latch in the ninth or deposit position causes the adding and subtracting totalizer to be positioned with the adding wheels 339 in cooperative relation with the actuators 23 1, so that the amount or" the deposit will be added on the adding elements of this totalizer.

Disconnection of the latch in this position also causes the type wheels (not shown) to be positioned to print the character indicating Ill) 302 counterclockwise. This movement of the lever 302 rocks the arm 30ft. also counter- :lockwise by means of a spring between these members. The counterclockwise movc ment of the arm 30%, due to the shape oi the cam slot 30;") therein, will rock the arm ill)? and shaft 308 in a cloc rwise direction.

l ast on the haft 308 (Fig. 3), appropriate to the balance bank, is an arm 510, the end of which normally lies just above pin 3-311, can ried by an arm 312, which is connected with the zero p p: al 2112. it can seen that when the shaft 808 .is rocked clockwise, the arm Elli"; Will also be rocked to a like extent, and will come into contact with the pin Elli, and thereby, hrough the arm 31L, rock the zero stop pawl 2112 in the balance bank to its ineffective position, in which position it will be held as long as the total lever remains out or its normal adding position. It h s already been des ribed hov: the latch. t of 1 balance bank is broken in the filth or vhen the new "l v balance position on operations balance is printed.

it will be noted that the latch of the balance bank may be'disconnected in three different )ositions, (Fig. 3), all of which will set t :e adding sice oi the adding and sub tin totaliz er, and it should be noted that made necessary by the fact that the is adapted to print in diti ereut column dependii tr and therefore, of the totalixer l i be s lected on each or these operations, the latch must bi disconnected in a c itl'eiuition.
